Summary

This paper is devoted to the characterization of FeCl3 solutions in isopropanol containing water. For this goal optical absorption and e.p.r. techniques have been used in conjunction with magnetization and Mössbauer data reported very recently. It is shown that in a 10−2 M solution of FeCl3 containing 0.4 M of water the main iron(III) species present in the solution are [FeCl4]− (55%) and [FeCl2(H2O)4]+ (20%) while the remainding 25% is due to dihydroxo dimers,

.

When the water concentration increases the [FeCl4]− anions are progressively destroyed, the main iron(III) species present in the solution being the dihydroxodimers and [FeCl2(H2O)4]+.

The variation of the concentration of the three species mentioned with the water content and FeCl3 concentration is presented in this paper.
